Absconding letter - Can they take action even when I am ready to give the gadgets?

I have resigned from my organization and the terms we're not good with me at the end so..I informed everyone the same and left the office. I have got relieved by my immediate reporting manager but not hr. I carry the gadgets with me now and I have said I am ready to return it to the office. HR is threatening me saying that legal action would be taken against me saying that I am absconding because I am carrying office property. Can they take action even when I am ready to give the gadgets ?

Just return the items to the company and take a receipt.
What were the terms and conditions of your job as per offer letter/appointment order?
Seek formal release by quoting immediate managers ok with exit.

Dear Frustrated:
NEVER, I repeat, NEVER speak ill of your employer - past or present. Was your resignation written, or you simply 'walked out' of the company, though you informed everyone about it?
Keeping office property, gadgets as you label them, HAVE TO BE RETURNED, the day the 'departure' is made official. Return them IMMEDIATELY, if you have not done so. HR's threatening, unfortunately, is appropriate.

Yes, your past employer is at liberty to lodge an FIR for stealing the company property. Did the company issue you any relive letter? If not, then return the gadget collect the receipt and release letter.

Hi,
You should have approached the HR before getting relieved,while informing all (as per your post only) and got the nod from your reporting Manager. You should have got a no dues then itself,at least the submission of company records is the last thing you should have done.
Immediate action required is go and submit office gadgets, convince/explain reasons to the HR for submitting them late.

Don't worry just put an email or call to them that when are you going to return the gadgets (means in a day or 2 days). Else go to your office directly by tomorrow and return them by taking a receipt of email.
Even if they send you absconding letter and you return the gadgets there won't be any problem. If you wont return, then they can proceed legally against you which would be a big problem in personal and professional.

Dear colleague,
It is not clear as to what makes you to hold on to the property in the first place when you are relieved from service by your boss and also that when you want to return the property. Why are you giving cause for the company to take action for the property in your possession which you have intention to return. Do it forthwith and be done with it.
